RELATIONSHIPS: When a relationship ends, a woman will cry and pour her heart out to her girlfriends, and she will write a poem titled 'All Men Are Idiots' Then she will get on with her life. A man has a little more trouble letting go. Six months after the breakup, at 3:00 a.m. on a Saturday night, he will call and say, 'I just called to let you know you ruined my life, and I'll never forgive you, and I hate you, and you're a total floozy. But, I want you to know that there's always a chance for us.'

This is known as the 'I Hate You I Love You' drunken phone call, and 99% of all men have made it at least once. There are community colleges that offer courses to help men get over this need.

LOCKER ROOMS: In the locker room men talk about three things: money, football, and women. They exaggerate about money, they don't know football nearly as well as they think they do, and they fabricate stories about women. Women talk about one thing in the locker: sex. And not in abstract terms, either. They are extremely graphic and technical, and they never lie.

MATURITY: Women mature much faster than men. Most 17-year old females can function as adults. Most 17-year old males are still trading baseball cards and giving each other wedgies after gym class. This is why high school romances rarely work out.

MAGAZINES: Men's BATHROOMS: A man has five items in his bathroom - a toothbrush, shaving cream, razor, a bar of Dial soap, and a towel from the Holiday Inn. The average number of items in the typical woman's bathroom is 437. A man would not be able to identify most of the items.

OFFSPRING: Ah, children. A woman knows all about her children. She knows about dentist appointments and soccer games and romances and best friends and favorite foods and secret fears and hopes and dreams. A man is vaguely aware of some short people living in the house.

DRESSING UP: A woman will dress up to: go shopping, water the plants, empty the garbage, answer the phone, read a book, get the mail. A man will dress up for weddings and funerals.

LAUNDRY: Women do laundry every couple of days. A man will wear every article of clothing he owns, including his surgical pants that were hip about eight years ago, before he will do his laundry. When he is finally out of clothes, he will wear a dirty sweatshirt inside out, rent a U-Haul and take his mountain of clothes to the Laundromat. Men always expect to meet beautiful women at the Laundromat. This is a myth perpetuated by reruns of old American sitcoms.

MIRRORS: Men are vain; they will check themselves out in a mirror. Women are ridiculous; they will check out their reflections in any shiny surface: mirrors, spoons, store windows, Joe Garagiola's head.

MENOPAUSE: When a woman reaches menopause, she goes through a variety of complicated emotional, psychological, and biological changes. The nature and degree of these changes varies with the individual. Menopause in a man provokes a uniform reaction...he buys aviator glasses, a snazzy French cap and leather driving gloves, and goes shopping for a Porsche.

TOYS: Little girls love to play with toys. Then when they reach the age of 11 or 12, they lose interest. Men never grow out of their obsession with toys. As they get older, their toys simply become more expensive and silly and impractical. Examples of men's toys: little miniature TV's. Complicated juicers and blenders. Graphic equalizers. Small robots that serve cocktails on command. Video games. Anything that blinks, beeps, and requires at least six 'D' batteries to operate.

MOVIES: Every actress in the history of movies has had to do a nude scene. This is because every movie in the history of movies has been produced by a man. Men will only show their butts, because butt size doesn't really matter.

JEWELRY: Women look nice when they wear jewelry. A man can get away with wearing one ring and that's it. Any more than that and he will look like a lounge singer named Ramone.

TIME: When a woman says she'll be ready to go out in five more minutes, she's using the same meaning of time as when a man says the football game just has five minutes left. Neither of them is counting time outs, commercials, or replays.

FRIENDS: Women on a girl's night out talk the whole time. Men on a boy's night out say about twenty words all night, most of which are 'Pass the Doritos' or Got anymore beer?'

RESTROOMS: Men use restrooms for purely biological reasons. Women use restrooms as social lounges. Men in a restroom will never speak a word to each other. Women who've never met will leave a restroom giggling together like old friends. And never in the history of the world has a man excused himself from a restaurant table by saying, 'Hey, Tom, I was just about to take a leak. Do you want to join me?'
